Jason Segel (Forgetting Sarah Marshall, I Love You Man) has joined the cast of The Adventurer’s Handbook. In February, Jonah Hill and his friend/writing partner Max Winkler (yes, Henry Winkler’s son) sold a spec screenplay, originally titled Adventurer’s Club, for a seven figure deal to Universal, with Lonely Island/SNL Digital Shorts/Hot Rod director Akiva Schaffer attached to direct. The story “centers on four 20-something guys who, inspired by a book [Mick Conefrey’s non fiction handbook], set out overseas in search of a mysterious location described in the book.” It has been described as “an edgy, broad comedy” likely to be R-rated.

Update: Apparently the Los Angeles Times screwed up and Nicholas Stoller is not involved with this project. The Playlist confirms that Akiva Schaffer is attached as the director of this project.

Back in February, it was reported that Jonah Hill and his friend/writing partner Max Winkler (yes, Henry Winkler’s son) sold a spec screenplay called The Adventurer’s Handbook (originally titled Adventurer’s Club) for a seven figure deal to Universal, and that Lonely Island/SNL Digital Shorts director Akiva Schaffer was in talks to direct. Well plans have changed.
